Mission 2: The Secret Rule

Help Leonardo Fibonacci to retrieve his research on the Golden Number.

The Netmath missions are problem-solving activities that stand out from the rest of the content offered on the platform. More complex, these activities immerse the students in an exciting adventure connected with the history of mathematics. Their mission? Restore all the math knowledge to help Alfred save the great city of Mathlantis threatened by Dr. Chaos.

In this second mission, the students are teleported to a farm in the Middle Ages where rabbits graze under a radiant sky. The farmer sees them. This is Leonardo himself. He is retired, but in dire straits: all his research on the famous Golden Number just blew away!

To retrieve the lost knowledge, the students have to solve a series of algebra problems. Doing so, they approach the Golden Number principle and the Fibonacci sequence in a very fun and simple way.

The missions are accessible for the 6th year of primary school through to the 3rd year of secondary school. However, they are not all available to students from the outset. Instead, students must unlock them by completing a set number of activities with a grade of 100%. Learn more
